specimens approach it in the rufous colour of their under tail- 

 coverts. 



The Yucatan bird is a somewhat paler form, and liidgway lias 

 distinguished it as subspccitically distinct under the name of 

 0. vetula jxillidiventris ; but a specimen from lirownsvillo, Texas, 

 is (|uite as palo and perfectly similar to Yucatan birds. 



Lastly, the North-eastern Mexican bird has been named by 

 IJaird as 0. maccalli, but specimens from this locality are typical 

 O. vetula, Wagl. 



On the whole, I do not think it possible that any of the above 

 forms can be considered even subspecifically distinct from typical 

 O. vetula. If any had a right to be so considered it would be the 

 0. plumljlcejis, (jiray.

 considerable vari:ition.
